bearing cage FDC Series ,The size is the same as Stieber DC series sprag cage, but torque is more higher than
1. Bearing cage FDC series is type of cage without inner or outer races. Its model and construction is followed for, this type provides higher torque and lower noise while fixed convenient.
2. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing.
3. The sprag space tolerance must not be exceeded. Inner and outer races must both have a minimum plain widthe, without any recess, to ensure the freewheel functions correctly as shown on following pages.
4. We can offer standard inner and outer races, as shown on the following pages.
5. Alternatively, races can be made in case hardened steel shafts, or housings, to the specification below.
6. Surface hardness of the finished pargt should be HRC 60 to 62°, for a depth of 0.6mm minimum.
7. Core hardness to be HRC 35 to 45°. Surface roughness not to exceed 22CLA . Maximum taper between races:0.007mm for 25mm Width.
